Bentham, G.—Notes on Caryopliylleae, Portulaceae, and some 
allied Orders. Linn. Jour. Bot. vi. p. 455. Caryopliylleae are 
distributed into tbe following tribes, viz. Sileneae, exstipulate, 
witb a gamosepalous calyx, hypogynous stamens and free 
styles; Alsineae, scarious stipules only in Spergula and Sper- 
gularia , free sepals, hypogynous or slightly perigynous sta¬ 
mens and free styles; and Poly car pace, stipulate, with free 
sepals, stamens as in Alsineae , and combined styles. Portula¬ 
ceae differ from Caryophylleae in the anisomery of the floral 
whorls ; the sepals usually 2, the petals 3 to 7, or 8. Mollugi- 
neae it is proposed to place in Monochlamydeae, near Phytolacca- 
ceae; and Paronychiaceae (limited to genera with 1-ovulate 
ovary and utricular fruit) near Amarantaceae. 
Critical observations follow upon the genera, &c., of Caryophyl¬ 
leae, Portulaceae, and Mollugineae. Heliosperma and JElisanthe are 
reduced to Silene; Melandrium, Viscaria, Agrostemma and Pe- 
trocoptis to Lychnis. The numerous genera of exstipulate 
Alsineae are reduced to 11, viz. PLolosteum , L., Cerastium, L., 
Stellaria , L., Brachystemma , Don, Aren aria> L., Buffionia, L., 
Colobanthus , Bartl., Thylacospermum , Penzl, Schiedea, Ch. and 
Sch., and Queria, Barth 
Bentham Gr.—Notes on Malvaceae and Sterculiaceae. Ibid. p. 97. 
Malvaceae. An essential character of this Order as distinguished 
from Sterculiaceae, Mr. Bentham finds in their one-celled 
anthers—one-celled not by abortion but confluence from an early 
stage of development. Bombaceae are included in Malvaceae, 
agreeing in their anthers, soft wood, cottony seeds, &c. A 
synopsis of the genera is given, followed by extended remarks 
upon each. Scleronema is a new genus of the subtribe 
Matisieae (Bombaceae), founded on a Brazilian plant of 
Spruce’s (No. 2548) near PLampea. "With Sterculiaceae proper, 
Buettneriaceae are united ; no tangible characters being available 
for their discrimination. A synopsis and critical notices of the 
genera are given. Dicellostyles is a new genus based on Kydia 
axillaris of Thwaites, and Cheirolcena on a Mauritius plant, near 
Bombeya. Under Glossostemon, are observations on the homologies 
of “ petiolar glands,”—referred by the author to a transverse 
4 dedoublement,’—and their relation to the anthers, especially of 
the tribe Buettnerieae , in which the ‘petiolar gland of the petal- 
leaf’ forms the apexof the hood connivent over the staminal column. 
Bentham, G.—On Inocarpus. Ibid. vi. 146. This genus, referred to 
Sapotaceae and Hernandieae is found by Messrs. Hooker and 
Bentham to be a true Leguminosea, near Btaballia , a tropical 
American genus of Mr. Bentham’s, which possibly may prove 
identical with Bocoa, of Aublet. Technical characters of the 
three genera are given.
